Matthew,

Unfortunately, I didn’t get much farther with this: Here is the output, any thoughts?

Thanks!

Dear Mark,

Can you confirm which version of FSL you are using?

Kind Regards

Dear FSL experts,

Hi. I sent an earlier post, but haven’t gotten a reply. I am running into problems with eddy_cuda, as follows:

We have a number versions of CUDA installed on our cluster, all of them fail. Version 7.5 gives me an out of memory error, and version 9.2 gives me a segmentation violation. My system admin thought that 9.2 was not compatible with eddy_cuda so he installed 9.1, but now I am getting a message which seems to indicate that it is looking for version 7.5. I get the message “libcudart.so.7.5: cannot open shared object file”.

Any assistance with this issue would be most appreciated, thanks!

Mark
